What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionIncisional hernia (IH) is a common complication after abdominal surgeries, whether conventional open or laparoscopic. Despite many efforts to reduce the incidence of IH, there is still a lack of consensus concerning the best approach for its prevention and repair. This pilot study evaluates a technique integrating perforatorpreserving anterior component separation with onlay mesh reinforcement at the midline and lateral external oblique incisions, addressing persistent challenges in tension management, vascular preservation, and recurrence reduction post-abdominal surgery. PATIENTS AND
methodsThis is a prospective pilot study conducted from January 2023 to January 2024 to evaluate the repair of large midline incisional hernias in 17 patients who underwent previous vertical midline incisions due to various indications. We used anterior component separation with perforator preservation along with onlay mesh reinforcement.
resultsAll cases underwent only mesh fixation. There were no intraoperative complications reported. The reported postoperative complications were wound seroma (41.2%), superficial wound ischemia (5.9%), and wound seroma with superficial wound ischemia (5.9%), while no complications were encountered in the rest of the cases (47.1%). There were no reported cases with deep wound ischemia and/or wound dehiscence.
conclusionThe anterior component separation technique with perforator preservation is a feasible and effective method for treating large incisional hernias with difficult midline closures. When paired with onlay mesh reinforcement for both the midline and lateral releasing incision, it provides satisfactory outcomes, low recurrence rates, and a manageable complication profile. The technique of the procedure should be tailored to each patient's specific condition.
